One is to open the ditch. From the highest point of seepage of the backwater embankment to the outer end of the embankment, several vertical trenches perpendicular to the embankment or oblique grooves of 40 to 60 degrees with the embankment are excavated, and the gutters of the vertical ditch are to be connected. Generally, the groove width is 0.3-0.5m, the depth is 0.5-1.0m, the groove distance is 6-10m, and the ditch is guided by the ditch. From the highest point of seepage of the backwater embankment to the outer end of the embankment, several vertical trenches perpendicular to the embankment or oblique grooves of 40 to 60 degrees with the embankment are excavated, and the gutters of the vertical ditch are to be connected. Generally, the groove width is 0.3-0.5m, the depth is 0.5-1.0m, the groove distance is 6-10m, and the ditch is required to be filtered. The layered paving filter material is filled with the excavation to prevent the trench wall from collapsing. The second is the reverse filtration. If the embankment is poor in soil quality, the section is small. Large area anti-filtration can be used for infiltration. First remove the surface debris from the water seepage site, and then layer the filling according to the filtration requirements. The third is to build a wall in the river. In the seepage section, fill the sticky soil bag along the water slope, build the front wall, and the size is determined according to the depth of the river and the degree of water seepage. Generally, the top of the wall is 3-5m wide, 1m above the water surface, and the length exceeds at least 5m at both ends of the seepage section. If the river has a large flow rate, piles of weaving fences or temple bags can be used to build partition walls, and then fill the soil. The fourth is the geotextile interception and diversion. Using the impermeability and good drainage performance of the geotextile, the geotextile with impervious performance is laid on the water-facing surface of the water-saving position to reduce the seepage of the dam or the dike by the flood flow, and the geotextile with good drainage performance is laid on the slope of the backwater embankment. The water immersed in the dam or the embankment is discharged, so that it can be "blocked in the lower row".
